Hi I'm considering installing a tankless electric water heater in my small 1 bedroom apartment in Torrevieja. Does anyone have any idea how much it'd cost me? I'd appreciate it if someone with an experience on this enlightens me please

Thanks

Uju

In a small apartment, your electricity supply is probably only 3.5 kw. Draw more current than that and you will trip the meter.

Most instantaneous hot water heaters draw much more than that, e.g. up to 24 kw. Even if the wiring is good enough to support such a high current, which is very unlikely, you'd have to pay for an initial boletín to confirm the allowable current, and the standing charge on your electricity bills would shoot up dramatically.

You can get a 3.5 kw heater, but even that would mean you couldn't have another electrical appliance in use at the same time. Such a low rated heater might provide enough hot water for washing, but I very much doubt whether it would provide enough for a shower:

Have you considered a gas unit? Neighbours of ours have a 2 bed house and use a gas water heater. They say a gas bottle lasts them 3-4 weeks for the 2 of them, when they are here full time. Theirs came from Leroy Merlín.

When we lived in France our tariff only allowed 3kw, so that extra half kilowatt we get here’s very welcome. We got rid of our gas water heater there and replaced with an electric  eighty litre tank. Switched on overnight, this gave us 80litres of 60°water, enough to switch the tank off during the day and use sufficient for our needs without any noticeable drop in temperature before switching it back on the next night.
